Basic kinematics variables: If the acceleration of an object is negative, the object must be slowing down.

Question

Quizplus · Accepted Answer

Acceleration is a vector quantity, meaning it has both magnitude and direction. Negative acceleration means the acceleration is in the opposite direction of the velocity. If the object is moving in the positive direction, negative acceleration will slow it down. However, if the object is moving in the negative direction, negative acceleration will actually speed it up.
